Added XSeries 13.7.1. Every material, sound and banner pattern resolves through it now, so the same jar runs on 1.8 up to the latest release.

Fixed the crash that killed every menu on 1.12 and older. The plugin read Material.PLAYER_HEAD directly, a field that only exists from 1.13, and the server threw NoSuchFieldError the moment a menu was drawn.

Fixed menu items turning into paper on 1.12 and older. Names like PLAYER_HEAD, LIME_DYE, OAK_SIGN, RED_BED and CLOCK are translated to whatever that version calls them, data value included.

Fixed the banner editor breaking on older servers. LOOM, LIME_DYE, WHITE_DYE and the coloured banners do not exist under those names there, and LOOM now falls back to a crafting table where it is missing entirely.

Fixed clan banners not loading on 1.12 and older, where every banner is a single BANNER material with a data value instead of RED_BANNER, WHITE_BANNER and so on. The base colour is read either way.

Fixed /clan banner upload refusing a banner held in hand on those same versions.

Fixed the pattern menu breaking on 1.21 and newer, where PatternType stopped being an enum. The shape list comes from the registry now.

Fixed player heads losing their skin on 1.11 and older, where setOwningPlayer does not exist yet. The old name based setter is used there.

Fixed light gray being called SILVER before 1.13 and showing up that way in menus. One name on every version now.

Fixed sounds doing nothing when the name belonged to another version. Sound names changed in 1.9 and again in 1.13, and anything unrecognised was dropped without a word.
